输入信号经过施密特触发器接入输入数据存储器。当无信号输入时，电压不确定。因为浮空输入既高阻输入，可以认为输入端口阻抗无穷大，这样可以检测到微弱的信号。（相当于电压表测电压，如果电压表内阻不够大而外部阻抗比较大，则电压表分压会比较小）。此时输入高电平即高电平，输入低电平即低电平。但是外 … See more 输入信号不经施密特触发器直接接入，输入信号为模拟量而非数字量，其余输入方式输入数字量。 See more 浮空输入在外界没有输入时状态不确定，可能对电路造成干扰。为了使得电路更加稳定，不出现没有输入时端口的输入数据被干扰（比如手碰一下电压就发生变化）。这时就需要下拉电阻（或上拉电阻）,此电阻与端口输入阻抗相比仍然 … See more 开漏输出即漏极开路输出。这种输出方式指场效应管漏极开路输出。需要接上拉电阻才能输出1。漏极经上拉电阻接到电源，栅极输出0时，场效应管 … See more 上拉输入与下拉输入类似，只是无输入信号时端口电平被拉到高电平。例如按键信号，当按下时输入低电平，松开时电平被拉到高电平。这样就不会出现按键松开时端口电平不确定的情况。即 … See more WebSTM32 GPIOS mode.
